Rugged and Ready

Zonal architecture simplifies this. Components are grouped into zones—front, rear, left door, right door— each managed by a central zonal computer. The central vehicle computer ties these zones together, ensuring seamless communication. By limiting the number of connections running across the car, wiring is lighter, assembly easier, and features can be added without complicating the vehicle’s architecture.

delivery at lower current, 48V systems support advanced functions that are difficult to implement on stretched 12V architectures. These include electrically driven compressors, active chassis and steering systems, and energy recovery functions that improve overall vehicle performance. In both electrified and hybrid platforms, this can contribute to reduced power and fuel con- sumption, and lower emissions while improving system responsiveness.

Simplifying architecture alone isn’t enough, and this is where 48V becomes particularly valuable. Higher voltage means lower current is required to deliver the same power. Thinner wires may be used along with small- er connectors, depend- ing on vehicle design and use case, achieving signif- icant wire weight. Such a reduction in electrical losses and mass supports greater overall vehicle efficiency, range and a reduced environmental impact. This efficiency gain has broader implications beyond wiring.

Rethinking connectors for safety and efficiency

As voltage increases, new design considerations emerge. Arcing can still occur during improper or under-load connection events. Connectors must maintain adequate creepage and clearance to prevent arcing, especially in environments where moisture, dust, or debris might be present. To address these challenges, a new Low Voltage Connector Standard (LVCS) has been developed specif- ically for 48V operations. Unlike legacy 12V connectors, these systems are designed with 48V safety margins and environmental conditions in mind from the outset.

TE Connectivity’s new standardized LVCS series addresses the challenges needed to meet global standards in 48V systems while maintaining consistent voltage ratings and reducing risk during assembly. Additionally, TE’s LVCS solution is de- signed for automation readiness.
